Protects you against undercooling during winter sports. The Jack Wolfskin Men's Icy Water Jacket is a functional insulation jacket with a System Zip and stretch inserts at the sides. It can be worn separately or used as lining for a compatible outer jacket. It is suitable for both options, thanks to the Microguard Maxloft synthetic insulation, which is not only warm but also wicks moisture away from the body quickly and effectively. The outer fabric is breathable and windproof – useful attributes when the jacket is worn on its own.
